Title: Door fastening assembly
Inventor: CHAMBERS MICHAEL BOOTH
IPC: E05B65/16
Filed: 1968-01-25
Abstract: 1,249,311. Door fasteners. BLAIR PRODUCTS S.A. 7 Jan., 1969 [25 Jan., 1968], No. 3885/68. Heading E2A. An assembly comprises, a door 21, a door frame 18 and a fastening device which includes an operating rod 6 rotatably mounted on the door, each end of said rod having a cam member 1 extending beyond the periphery of the door and a pair of keepers 2 on the door frame each of which includes a pin 12, each cam member being adapted to engage one of the pins during door closing whereupon rotation of the rod causes the cam members to slide about the pins thereby drawing the door towards its closed position in which position the rod and pins are co-axial. Each cam member in cross-section is generally U-shaped with a concave pin engaging inner surface 11 having a nose portion with a radius of curvature greater than the radius of curvature of the keeper pins and an inner portion having a radius of curvature substantially equal to the radius of curvature of the keeper pins, the cam members being adapted to slide about the pins from the nose portions to the inner portions which latter engage the pins when the door is closed. Each of the cam members has a camming surface 3 adapted to engage a surface of the corresponding keeper in door closing to produce stabilizing stresses between the door and frame in the direction of extent of the rod.

Abstract: 929,445. Maximum demand meters. CHAMBERLAIN & HOOKHAM Ltd. Jan. 24, 1962 [Feb. 2, 1961], No. 3943/61. Class 106 (3). A maximum demand meter comprises a spirally-wound spring 10 one end of which is connected to an intermittently rotatable toothed wheel 11 which periodically causes re-setting of a pointer driving member, the other end of the spring 10 is connected to a ratchet wheel 24 for re-winding the spring, a looking lever 22 inhibits re-winding after the wheel 24 has turned through a predetermined angle and when the wheel 11 has turned through a predetermined angle a star wheel 17 releases the lever 22 to allow a further re-winding operation. A solenoid 14 periodically causes a lever 13 of an escapement mechanism to release the wheel 11 for rotation through half a revolution to drive a pinion 15 in the re-setting mechanism. In each revolution of the wheel 11 a tooth 16 advances a star wheel 17 one tooth and after five revolutions corresponding to ten re-setting operations, a pin 18 on one tooth of wheel 17 engages a pin 19 on a tooth of another star wheel 20. The wheel 20 turns with it a cam 21 so that the lever 22 escapes from the recess in the cam 21 and frees the pawl carrying arm for oscillation by cam 25 so that the pawl 23 drives the ratchet wheel 24 to wind the spring 10. Specification 929,444 is referred to.

The solid derivatives can be used as such or blended with other fuels.  A binder may be added and regulators are usually present.  Oxidizers such as nitrates or perchlorates of potassium, sodium, magnesium, lithium or ammonium are usually present.  The solid fuels or blends may be used as fuels for rockets, high pressure jets for cutting, oil well perforation, drilling operations, and underwater propulsion devices.ALSO:The invention comprises an organic boron hydride derivative containing boron to hydrogen linkages and constituted by the addition product of a boron hydride and a hydrocarbon compound having at least one vinyl group bonded to the boron atom.  The preparation of vinylated boron compounds is described in Specification 873,180.  The valencies of the boron not bonded to vinyl groups may be bonded to hydrogen or hydrocarbon groups, preferably methyl or ethyl, but including phenyl, benzyl and octyl.  The boron hydrides used include diborane, tetraborane pentaboranes (9 and 11), hexaborane, decaborane and ethyl-decaborane.  Alkyl boron hydrides may also be used.  The boron hydride and boron vinyl compound may be reacted at temperatures between -50 DEG C. and 100 DEG C., preferably in stoichiometric quantities.  Non-reactive solvents such as tetrahydrofuran, hydrocarbons or mixtures thereof may be used, and a vinyl polymerisation catalyst may be present.  The reaction may be effected in the presence of U.V. light.  The products may be monomeric or polymeric, and the cross-linking may occur between the polymeric chains, the extent of this cross-linking determining whether a glassy, liquid or solid product is obtained.  The products may be used as fuels and propellants.

Patent GB-709563-A (GB)
Title: Neutralization of capillary-active agents
IPC: C09K23/00
Filed: 1951-02-21
Abstract: Capillary active sulphated or phosphated organic compounds containing a group hydrolyzable to the carboxylic acid group are neutralized by means of a neutralizing agent in the presence of a water-soluble weak acid having a dissociation constant between 1X10-4 and 1X10-10 and/or a salt of such acid, characterized in that the capillary active agent, neutralizing p  agent and the weak acid and/or its salt are brought into reaction in aqueous solution in such balanced amounts that by buffering action a pH range between 5 and 9, preferably between 6 and 7 is uniformly maintained in the reaction zone during the whole of the neutralization process.  Hydrolysis of the capillary active agent is thereby reduced or obviated.  Batchwise neutralization may be effected by simultaneous addition of capillary active agent and neutralizing agent to a solution of the weak acid and its salt in pure water in such a proportion in relation to the solution that the solution has a pH between 5 and 9.  The process may be operated continuously by simultaneous addition of capillary-active agent, neutralizing agent and weak acid and/or its salt to an aqueous solution of previously neutralized capillary active agent, weak acid and its salt in such a proportion in relation to the solution that the pH of the solution is between 5 and 9 and removal of corresponding quantities of neutralized solution in such a manner that the composition of the solution remains approximately constant. Alternatively, a premixed mixture of capillary active agent and weak acid and the neutralizing agent or a premixed mixture of neutralizing agent and weak acid and/or its salt and the capillary active agent may be simultaneously so added to the aqueous solution of previously neutralized capillary active agent.  Specified weak acids are ortho-, pyro- or polyphosphoric acid or mixtures thereof.  In this connection reference is made to the addition of primary and secondary phosphates to the solution in the reactor or their formation therein from orthophosphoric acid or salt therein.  A solution of di- or tri-sodium phosphate may be used as neutralizing agent.  In examples: (1) a sulphonated monoglyceride is neutralized with caustic soda by the continuous process described in Specification 477,521 with and without the simultaneous addition of a controlled amount of orthophosphoric acid and the buffered reaction mixture yields a product having a higher combined SO3-content per mol. of combined aliphatic acid in the sulphated glyceride; (2) a mixture of sulphated monoglyceride and sulphuric acid and caustic soda are simultaneously added to a buffer-solution prepared from distilled water, phosphoric acid and caustic soda.
